Doctrine sits in between strategy and plans. It is more specific than the strategy, but also more versatile than plans, or rules. Think of it as heuristics, or guidelines: the purpose of doctrine is to enable an individual to know what to do in a situation that's consistent with the strategy and achieves the objectives of a plan, but with flexibility, with autonomy, for the individual, in the circumstance. And the creation of effective business doctrine, I believe is going to be critical for the transition of business in the next century.
